Pakistan, Aug. 23 -- Replicating human eye has always been the biggest challenge for researchers and scientists for years. But to everyone's surprise team of researchers in Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have made a breakthrough in coming up with a revolutionary optical instrument.

This new type of lens combines flat lens technology previously created by the same researchers, and the development of artificial muscles. This allows it to focus on real-time and is not bulky like the typical lenses used in today's instruments. It's not able to adjust for astigmatism and image shift, but it's a step in the right direction.

The flat lens component used in the above-mentioned electronic lens is called...
